DC2807A

DC2807A demonstration circuit features the LTC®6560 single-channel trans-impedance amplifier (TIA) with output multiplexing. The LTC6560, which features 74Kohm trans impedance gain and 30µA linear input current range, is ideal for LIDAR receivers using avalanche photodiodes (APD). The LTC6560 operates from 5V single supply and consumes only 90mW. Utilizing the LTC6560’s output MUX, multiple LTC6560 devices can combine into a single output. The LTC6560’s fast overload recovery makes it well suited for LIDAR receivers. The LTC6560’s single-ended output can swing 2VP-P into a 100 ohm load.
